Hi, I am having a little problem with Ollydbg as I have no idea of how to change "Arg2" to specific string.
There is "Arg1" and "Arg2". Arg1 is the name in the windows registry and Arg2 is the data. Arg2 is somehow produced and is being checked if it's right at every app launch. Therefore if I change manually these 2 values in windows registry and start application then these values will change back.
Could you provide with some help or a hint of how to change Arg2 to a desired string, or how to 'hack' 'Arg2 value generating system' ?

This is what I get if I Step Into: PUSH ECX "Arg2" :
